Diễn đàn hỗ trợ Firefox

Fire fox is automatically playing videos/sound or both if I click on a tab that has that or also in facebook, etc. How do I stop this? I want to be able to click play when I want to hear/see something.

!. link to youtube only flashes then plays only audio. Full video requires opening link in a new private browser window

2. Typing into search bar for Duck Duck Go in new tab page types directly into active bar...

3. Active bar is no longer at the top but is in Bookmarks toolbar...

I suspect some update problem.

I was able to stream news from CTV news site but for some unknown reason I cannot stream it like I used too I cannot figure out why! Something must be wrong with my setup. Please help me fix my problem.

When I listen to music via Firefox, my computer goes into sleep mode after 15 minutes (windows close and password is required)^)^. I've looked everywhere to find a solution to this problem, but I can't find one... Can you help me?

When switching to full-screen mode in Firefox while watching a video, the cursor won't disappear automatically until you move it. This issue affects all players except the native Firefox player. The bug appeared in version 143 and higher (affects all builds, including stable, Beta, and Nightly). I've tested the issue by rolling back the browser to versions 140 and 142.0.1, and everything works fine. There's a thread about this issue on the Bugzilla forum. macOS versions Tahoe 26.0 and Sequoia 15.7 are currently running. I can't test on other systems.

Today my Facebook has no sound. My laptop has sound. Youtube has sound, NBC has sound, Amazon Music has sound, NPR has sound, it's just Facebook that is WITHOUT SOUND. So that is why I am wondering, does Firefox/Mozilla have sound settings that I might access to fix something like this?

I have already tried rebooting the laptop. Rebooting the browser. Rebooting Facebook. Thank you in advance for whatever help you might offer, Pamela
